In some contemplated embodiments, the controller 31 determines the occupant's position based on information from a pressure sensing topper. In some contemplated embodiments, the controller 31 determines the occupant's position based on the gas pressure in bladders in a powered mattress 30.

The communication device 33 is configured to communicate information between the person support system 14, the lift system 12 and/or other equipment in the vicinity, the communication system 16, and the hospital network 20. In some contemplated embodiments, the communication device 33 serves as a hub for a room and information from other devices in the room is sent to the communication device 33 to be stored in memory on the person support system 14, or communicated to the communication system 16 or hospital network 20. In some contemplated embodiments, the communication device 33 communicates wirelessly with the communication system 16, other equipment in the room (including the lift system 12) and/or the hospital network 20. In other contemplated embodiments, the communication device communicates via a wired connection with the communication system 16, other equipment in the room (including the lift system 12) and/or the hospital network 20.

The lift system 12, according to one contemplated embodiment, includes an overhead lift system 34 as shown in FIG. 3. In some contemplated embodiments, the lift system 12 includes a floor lift system 36 (i.e., a powered sit-to-stand lift) shown in FIG. 4, or other person lifting devices, including the various person lifting devices sold by Liko. The lift system 12 includes a rail 38 coupled to a ceiling of a room and a lift assembly 40 configured to move along the rail 38. The rail 38 includes a track 42, a stop 44 coupled to the track 42, and a conductor 46 along the track 42. In one contemplated embodiment, data and power are communicated over the conductor 46, which can allow a power source in the lift assembly 40 to be recharged, and can allow the lift assembly 40 to communicate with the person support system 14, the communication system 16, and/or the hospital network 20. In some contemplated embodiments, portions of the rail 38 and lift assembly 40 are constructed as disclosed in U.S. Patent Publication No. 2012/0000876, which is incorporated herein by reference.

The lift assembly 40 includes, a lift 48, a strap 50 configured to be extended and retracted by the lift 48, a sling bar 52 coupled to an end of the strap 50, a sling 53, and a control system 54 as shown in FIG. 3. The lift 48 includes a carriage 55 configured to engage the track 42 of the rail 38 and move the lift assembly 40 along the rail 38, a housing 56 coupled to the carriage 55, motor 58 positioned in the housing 56, and a drum 60 coupled to the shaft 61 of the motor 58 and configured to raise and lower the strap 50 as the motor 58 rotates the drum 60 as shown in FIG. 5. In one contemplated embodiment, the carriage 55 includes a conductor (not shown) configured to electrically couple with the conductor 46 on the rail 38. The sling bar 52 is coupled to the end of the strap 50 and includes aims 52 with sling coupling portions 64 at the ends of the arms 52. The sling coupling portions 64 are configured to receive and removably retain a portion of the sling 53. The sling coupling portions 64 include a retaining element 66 that is configured to prevent the sling 53 from disengaging the coupling portions 64.

The sling 53 is used to support the person being moved by the lift assembly 48 and includes a main body portion 68, leg portions 70, and connecting straps 72. In one contemplated embodiment, the sling 53 can be one of the slings sold by Liko, such as, the Solo HighBack model 25 sling as shown in FIG. 7. In some contemplated embodiments, the sling 53 includes an RFID tag 74 coupled to the sling 53 that includes information related to the sling, such as, the sling model number, the manufacturing date, the size, the serial number, the date the sling was last inspected, the performance characteristics of the sling, the patient's ID that the sling has been assigned to, and other related information. In one contemplated embodiment, the RFID tag 74 is positioned between the layers of material adjacent to the connecting straps 72. In some contemplated embodiments, the RFID tag 74 can be replaced with a magnet (not shown).

The control system 54 includes a user interface 76, a controller 78, a communication device 80, sensing elements 82, and a battery 83. The user interface 76 includes a pendant 84 with a display 86 and buttons 88 thereon. The buttons 88 provide input to the controller 78 indicative of a user's desire to raise and lower the sling 53, and the display 86 is configured to display information related to the lift system 12, the patient, the room, the facility, and other information. In some contemplated embodiments, the pendant 84 includes an accelerometer 82 that is configured to determine when the pendant's 84 orientation has changed such that the button 88 that causes the lift 48 to lift the person up is pointing downward, and re-assign the button function to the button 88 that is currently pointing upward, so that when a user presses the button 88 that appears to make the lift 48 lift the person, the lift 48 will lift the person (instead of lower). In some contemplated embodiments, the battery 83 is charged via the pendant 84 when the pendant 84 is docked in a docking station (not shown). In another contemplated embodiment, the battery 83 is charged via the conductor 46 on the rail 38. In other contemplated embodiments, the battery 83 is recharged over an Ethernet connection or over a communication bus (i.e., the High Speed DC-CANTM power-line modem transceiver sold by Yamar Electronics).

The sensing elements 82 are configured to sense various operational characteristics of the lift assembly 40 and provide an input signal to the controller 78. In some contemplated embodiments, the controller 78 uses information sensed by the sensing element 82 to determine at least one of the following: the accumulated “drive time” (i.e., in seconds), the amount of weight lifted by the lift system 12 to date (which can be combined with the total weight lifted by other lifting devices 12 on the same wing of the care facility to show the total weight lifted over the entire wing of the care facility), the “drive time” since the device was last serviced (i.e., in days), the accumulated “capacity consumption” for the up/down driver motor (i.e., in amps), the number of resets of a service indicator, the number of accumulated activation of upper current limiting circuit, the number of started and completed and not completed charging cycles, the number of activations of the upper and lower end limit switches, the number of completed lift cycles, the battery level, the number of times the device was overloaded, the percent of the load carried by the patient or the lift, the increase in strength of the patient over time, the patient's weight history, the decrease in assistance of the lift over time, and the number of lift events (compliant lifts and non-compliant lifts).

The sensing elements 82 can be one or more of a variety of sensing devices. In one contemplated embodiment, the sensing elements 82 include an accelerometer positioned within the sling bar 52 that is configured to sense when the sling bar 52 is tilted to one side, which may indicate that the sling 53 is improperly connected to the sling bar 52. In this embodiment, upon detecting the tilted sling bar 52, the lifting motion can be stopped and the user can be alerted about the condition and asked to check the connection of the sling 53 and the sling bar 52 before lifting can resume. In some contemplated embodiments, the sensing element 82 includes a force sensor that is used to measure the weight of the patient being supported by the lift system 12. In some embodiments, the sensing element 82 includes an energy sensor (i.e., an electric current sensor) that is configured to sense the amount of energy being used by the lift system 12 to lift the patient and/or the amount of charge left on the battery 83.

In another contemplated embodiment, the sensing element 82 includes an optical strap scanner that is configured to assess the condition of the strap 50. In some contemplated embodiments, different wavelengths of light can be used to scan the strap 50. In some contemplated embodiments, the optical strap scanner is the c2060 seat belt inspection system sold by FibreScan. In some contemplated embodiments, the optical strap scanner (or other optical sensing device as discussed further below) can be used to sense the distance a person is moved by the lift system 12. In one contemplated embodiment, the optical strap scanner can measure the distance using marks on the strap 50 that are spaced apart a predetermined distance. In one contemplated embodiment, a line on the strap 50 at predetermined intervals can be used. In some contemplated embodiments, patterns can be shown on the strap and can be used to determine if the strap 50 was moving up or down. In one contemplated embodiment, a repeating pattern of three lines of varying length and/or thickness can be used. In another contemplated embodiment, a gray scale coding pattern can be used to, when sensed by the optical strap scanner, determine the distance, speed, and direction the strap 50 has moved.

In another contemplated embodiment, the sensing elements 82 are configured to sense when a sling 53 is connected to the sling bar 52. In one contemplated embodiment, the sensing element 82 a hall-effect sensor that is configured to sense when a sling strap 72, including a magnet coupled thereto, is attached to the sling connector 64. In another contemplated embodiment, the sensing element 82 is a switch that is coupled to the retaining element 66 and is configured to sense when the retaining element 66 is opened and closed, which could signify the sling strap 72 being attached to the sling connector 64. In another contemplated embodiment, the sensing element 82 is an optical sensor that is coupled to the sling connector 64 and is configured to sense when the sling strap 72 is positioned in the sling connector 64. In situations where it is determined that the sling 53 is not properly coupled to the sling bar 52, the user can be alerted and the lift 48 can cease movement of the strap 50 until the user ensures that the sling 53 is properly coupled to the sling bar 52.

In another contemplated embodiment, the sensing element 82 includes a RFID reader coupled to the sling bar 52 and configured to read RFID tags coupled to equipment within a predetermined distance of the sling bar 52. In one contemplated embodiment, the RFID reader can sense when a sling 53 is positioned within a predetermined distance of the sling bar 52 and can be indicative of the sling 53 being attached to the sling bar 52. In some contemplated embodiments, sensing that the sling 53 is near the sling bar 52 in combination with sensing that a sling bar is supporting a weight is indicative of the sling 53 being attached to the sling bar 52. In some contemplated embodiments, the RFID reader is coupled to the sling. In some contemplated embodiments, the RFID reader is coupled to or integrated into the user interface 76 (i.e. pendant 84). In some contemplated embodiments, the RFID reader is coupled to or integrated into the lift 48. In some contemplated embodiments, multiple RFID readers can be used to triangulate the location of the different RFID tags 74 to see if a sling 53 is coupled to the sling bar 52. In some contemplated embodiments, the RFID reader can alert a user as to when an unknown or unapproved sling 53 is being used with the lift system 12. For example, if the incorrect size or weight rated sling 53 is being used with the patient, the system can alert the user. In another example, if the sling 53 is not assigned to the person, the user can be alerted. In some contemplated embodiments, the system can also inform the user which model sling 53 would be appropriate for them to use with the patient. In some contemplated embodiments, the system can alert the user as to the condition of the sling 53. In other contemplated embodiments, the RFID reader can also write to the RFID tags to store performance information, association information, or other information about the caregiver, patient, facility, sling condition/status, or other information. In some contemplated embodiments, the RFID reader is configured to read an RFID bracelet worn by the patient.

In some contemplated embodiments, the controller 78 can use the RFID reader to associate the person support system 14, the sling 53, the patient, the caregiver, and other devices adjacent to the RFID reader. In one contemplated embodiment, the RFID reader is coupled to the sling bar 52 and is configured to read any RFID tags within a predetermined distance, i.e., three feet, from the reader and store in memory, or write to the RFID tags, what devices are being used together to associate them with one another. In some contemplated embodiments, the RFID reader can be used to associate equipment (i.e., a lift and/or a sling 53) and people (i.e., a caregiver and/or a patient) with one another and the room if they have RFID tags and are in the vicinity of the RFID reader. In some contemplated embodiments, other equipment in the room, the person support system 14, medications, and other devices including RFID tags can be associated with one another when they are in the vicinity of the RFID reader.

The controller 78 is configured to receive inputs from the user interface 76 and the sensing elements 82 and control the operation of the lift 48 as a function of the input. The controller 78 includes a processor 90, a clock 92, and memory 94 as shown in FIG. 8. In some contemplated embodiments, the clock 92 is removed and date and/or time information is provided by the information management system 18 or through the hospital network 20. The processor 90 is electrically coupled to memory 94, the battery 83, the clock 92, the sensing elements 82, the communication device 80, and the user interface 76. The processor 90 is configured to execute instructions stored in memory 94. In some contemplated embodiments, the instructions define procedures that cause the processor 90 to collect and process information sensed by the sensing elements 82 that is related to the lift system 12 or the patient being moved by the lift system 12 or the person support system 14 or the care facility or other equipment in the vicinity of the lift 48.

In one contemplated embodiment, the instructions define a procedure 300 that determines when a lift event has occurred as shown in FIG. 9. Procedure 300 begins with step 302 where the processor 90 receives a signal from a sensing element 82 indicative of a sling 53 being coupled to the sling bar 52. In one contemplated embodiment, a sensing element 82 is coupled to the sling bar 52 and is configured to sense when the retaining element 66 is moved to allow the sling 53 to be attached to the sling bar 52. In one contemplated embodiment, the sensing element 82 is a contact sensor that is in a first state when the retaining element 66 is closed (as shown in FIG. 9) and in a second state when the retaining element 66 is opened to allow the sling straps 72 to be coupled to the sling bar 52. In some contemplated embodiments, a mechanical switch, hall-effect sensor, optical sensor, RFID reader, magnetic sensor, or force sensor (sense weight) can be used to determine the state of the retaining element 66 or the engagement of the sling straps 72 with the sling connector 64. In some contemplated embodiments, the sling 53 includes RFID tags 74 and/or magnets coupled thereto as previously discussed.

In step 304, the processor 90 receives a signal from the sensing element 82 when the sling 53 is uncoupled from the sling bar 52. In one contemplated embodiment, the sensing element 82 indicates that the retaining element 66 was moved a second time. Upon determining that the retaining element 66 has been opened twice, the processor 90 indicates that a lift event has occurred and stores information related to the lift event, including the time, in the memory 94.

In some contemplated embodiments, a lift event has not occurred unless steps 302 and 304 are true and an operational characteristic of the lift 12 has been sensed in step 306. In one contemplated embodiment the operational characteristics include, but are not limited to, the distance the person has been moved, the weight of the person supported on the lift 12, the amount of time the lift 12 was being used, the amount of current used to power the lift motor 58, and the duration the buttons 88 on the pendant 84 were pressed and held. The distance the person is being moved can be determined using a potentiometer configured to rotate as the strap 26 is extended and retracted. The distance the person is being moved can also be determined using an optical sensor coupled to the lift housing 56 and configured to sense patterns on the strap 50 as the strap 50 moves past the sensor. In one contemplated embodiment, the pattern includes three indicators (such as, 3 horizontal lines of increasing length on the flat side of the strap 50) that repeat along the length of the strap 50. Using patterns of indicators enables the processor 90 to determine the direction, distance, and speed the strap 50 is moving. In some contemplated embodiments, a single indicator spaced apart at predetermined intervals is used to indicate the distance traveled. In some contemplated embodiments, the strap inspection system checks the condition of the strap 50 and senses the distance the strap 50 has traveled. In some contemplated embodiments gray scale coding can be used to determine the distance, the direction, and the speed at which the person was moved. In some contemplated embodiments, the gray scale coding can be located on the motor shaft 61 or edge of the strap 50 and an optical sensor can be used to read the code. In other contemplated embodiments, the marks can be on the edges of the strap 50.

In another contemplated embodiment, step 306 includes sensing when other devices having RFID tags on them are proximate to the lift bar 52. Generally, when in storage, the strap 50 and the sling bar 52 are retracted. In this position, an RFID reader coupled to the sling bar 52 and configured to read RFID tagged objects within 3 feet of the reader would generally not be in communication with any RFID tags. When the lift 12 is being used, the sling bar 52 is lowered and brought to a location where the RFID tag 74 on the sling 53 and the caregiver's badge and/or the person support system 14 can be read. In some contemplated embodiments, the RFID reader can associate objects having a RFID tag within the 3 foot radius of the RFID reader. In one example, the RFID reader can associate a sling 53 including an RFID tag with a caregiver and a person support system 14 within a predetermined distance from the reader. The RFID tags on the sling 53 can include information about the sling model number, performance characteristics of the sling (i.e., max load is 500 lbs), size of the sling 53, and other characteristics of the sling 53.

In one contemplated embodiment, the instructions define a procedure 400 that determines when a lift should have been used, but was not used to move a patient as shown in FIG. 10. Procedure 400 can be executed on the person support system 14, the lift system 12, or on a remote system, including the information management system 18. Procedure 400 begins with step 402 in which the processor 90 receives information from the person support system 14 indicative of a change in position of a person supported on the person support system 14. In one contemplated embodiment, the change in position can be detected based on a change in the person's center of gravity exceeding a predetermined threshold. In another contemplated embodiment, the change in position can be detected using a pressure sensing mat positioned on the mattress 30 (or using pressure distribution in bladders in an active mattress 30) and measuring the difference between an initial pressure profile and a new pressure profile.

In step 404, the processor 90 receives information from the EMR system indicative of whether the person is required by the hospital's protocol to be moved using a lift. If the person is, the processor proceeds to step 406.

In step 406, the processor 90 receives a signal indicative of whether a caregiver was present when the movement occurred. In one contemplated embodiment, the location of the caregiver at the time of the movement can be provided by an asset locating and tracking system. In one contemplated embodiment, the location of the caregiver at the time of the movement can be determined by the RFID reader 82 coupled to the sling bar 53. If the RFID reader coupled to the sling bar does not sense the RFID tag in the caregiver's badge at about the time the movement occurred, the indication may be that the caregiver was not present at the time. If the processor determines that a caregiver was present, the processor proceeds to step 408.

In step 408, the processor 90 receives a signal indicative of whether or not the lift system 12 was used at the time the movement occurred. Any of the operational characteristics previously mentioned can be used to determine whether the lift system 12 was operated. If the lift system 12 was activated, the processor 90 indicates that the lift event complied with the care facility's lift protocol. If the lift system 12 was not activated, the processor 90 indicates that the lift event did not comply with the care facility's protocol.

The communication device 80, as shown in FIGS. 12 and 13, is configured to communicate information about the lift 12 and the patient associated with the lift to a plurality of locations and/or devices as shown in FIG. 11. In one contemplated embodiment, the communication device 80 communicates information that is charted in an electronic medical record (EMR). In one contemplated embodiment, the communication device 80 is a radio frequency transceiver. In other contemplated embodiments, the communication device 80 can be configured to communicate with the information management system 18 through a fiber-optic cable, over a power connection (i.e., where power is communicated to the lift system 12 via the rail 38 as shown in FIGS. 5 and 14 and), over a LIN Bus, via Bluetooth or Wi-Fi or NFC (near field communication) or other wired or wireless communication methods. In one contemplated embodiment, the devices and locations the information is communicated to includes the pendant 84, a caregiver's mobile device (i.e., cell phone or tablet computer or the like), control panels on the hospital beds 14 (i.e., beds associated with the lift system 12), a computer terminal at a nurse station, and/or a television in the patient's room.
